Simple patterns where NP couples solely to muons can in fact explain the discrepancies between the SM and experiment very well. However, it turns out that structures with additional LFU contributions can describe data even better [1]}. This means that allowing simultaneously for presence of LFUV and LFU NP effects, one can further improve the goodness of the global fits. Indeed, some of these hypotheses exhibit the highest significance among all studied scenarios [2]}, [3]}, [4]}, [5]}. However, in such a model-independent approach it is difficult to be certain that the most optimal and/or minimal NP hypothesis have been found due to the large number of possibilities. One way to make progress is to use UV complete (or simplified) models where the number of generated scenarios is usually smaller. In this context several models giving rise simultaneously to LFUV and LFU effects have been proposed in the literature, including 2HDMs [6]}, leptoquarks [7]}, [8]}, \(SU(2)_L\)  triplets vector bosons [9]} and models with vector-like quarks [10]}, [11]}.
